The Automotive composites Alliance is pushing thermoset plastic composites for a wide variety of applications in hybrid cars, including modules that contain the battery pack, electronic controller and wiring harness. In the US the modules are typically made of several metal stampings which are assembled. Use of composites could reduce the module to two pieces with major savings in weight as well as tooling investment. “Unlike metal, composites don’t conduct electricity, therefore providing an extra safety advantage,” says the Alliance report. “They also won’t corrode and allow integrated airflow cooling in the module’s tunnel, all adding to longer battery life.”
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
